MOVABLY-SUSPENDED MOTOR-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 674,753, dated May 21,1901.

Application filed November 9, 1899- Serial No. 736,408. (No model.)

To all whont it may concern.-

Be it known that I, J OHANNES BENNIK, a subject of the-Queen of theNetherlands, and a resident of No. 7 Tunnelstrasse, in the city ofHamburg and German Empire, have in: vented certain new and usefulImprovements in Movably-Suspended Motor-Elevators, of which thefollowing is a specification.

This invention has relation to elevators, and more particularly tobucket and similar elevators ordinarily employed in handling coal,grain, and like substances and more especially adapted for transferringsuch substance from the hold of a vessel to a storagebuilding or to avehicle.

The object of myinvention lies, primarily, in the general constructionof the elevator with a view to economy in space, facility in handling,reduction in weight, and adaptability to its being stored in a compactform either on board ship or elsewhere.

To these ends the invention consists in locating the prime mover withinthe upper driving-pulley of the elevator, whereby the necessarytransmission devices from such prime mover are dispensed with, togetherwith the usual platform at the head of the elevator and from which suchprime mover has heretofore been supported, thus saving not only a largeamount of space necessarily occupied by such platform, but materiallyreducing the weight and enabling me to provide means for connecting theelevator to a block and tackle on board ship, whereby the shifting ofthe elevator from point to point and the raising and lowering thereofare materially facilitated, dispensing with the usual mechanicalappliances for moving the elevator longitudinally or giving it theproper angle relatively to the cargo to be transferred.

The invention further consists in structural features and combinationsof cooperative parts; but that my invention may be fully understood 1will describe the-same in detail, reference being had to theaccompanying drawings, in which- Figures 1 and 2 are elevations of theupper and lower parts of my improved bucket elevator. Fig. 3 is a likeView illustrating the 50 same as suspended from block and tackle onboard ship, the latter being partly broken away to show the elevatorpassing through the hatches into the lower hold. Fig. 4c is a section ofthe elevator-head, taken on lineA B of Fig. 5, which latter is a sectiontaken at right angles to said line A B.

The elevator-head comprises a hood or shield constructed with adischargespout 0L and provided diametrically opposite said spout, orsubstantially so,with a gate 0 through which ready access is had to theparts covered by said hood or shield. Cheek-plates h and h are securedto either side of the aforesaid hood and are provided with bearings, inwhich are secured journalsp p, on which the bucketchain drive-wheel a,revolves and which serve as supports for a framing q, that carries theprime mover, which, as shown in the drawings, is an electric motor, itindicating the field-magnets, and "rthe armature, mounted on shaft 3,intersecting the axes of the journals p p and having its bearings in theaforesaid frame q. One end of the shaft 8 is provided with Worm-teeth ormay carry a worm s in gear with a worm-wheel so on a spindle which hasits bearings in bracket-arms on frame q above the shaft 3 and parallelwith the journals 1) p, said spindle carrying two spu r-wheels y y,gearing with internal gears zz'ofthedriving-pulleya. Powerissupplied tothe electric motor through insulated wires to o, contained in a sheathor tube w, of insulating material, said wires being carried to the motorthrough one of the pulley-journals p and connected up in any well-knownmanner. Theupperattenuatedendsof theeheekplates h h are connectedtogether by a bolt is, so that the elevator-head may be readily securedto or suspended from block and tackle Z, as shown in Fig. 3.

The hood or shield a at its lower end is of sections f, each sectionhaving bolt-flanges g g, by means of which they are detachably securedtogether and to the tubular portion of the elevator-head.

For the purpose of stiffening the elevatorleg the side plates andleg-sections are provided with straps i for the reception of the ends ofbracing or stiffening bars 6, which latter are preferably made of Woodto reduce the weight as much as possible. The lower leg-section hasbearin gs for the lower bucketband pulley b, as shown in Fig. 2, which,as usuahis rotated by the travel of said band.

Of course it will be understood that the endless bucket-band d is madeof sections detachably secured together by means of any well-known andcommonly-used detachable fastening devices, which I have deemedunnecessary to illustrate, so that said band may be lengthened orshortened in accordance with the lengthening or shortening of theelevator-leg.

From the above description the objects of my invention as well as theoperation and mode of using and handling the elevator will be clearlyunderstood and willtherefore need no further elucidation.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is

1. A pendulous bucket elevator, comprising a head and leg, a bucket-bandpulley in said head, a like pulley at the lower end of the leg, a motorfor the pulley in said head and means for supplying motive power theretofrom a source distant therefrom, said elevator-head provided with meansfor suspending the same from a flexible support, for the purpose setforth.

2. A portable bucket elevator comprising a head and leg composed ofseparable sections, bucket-band pulleys in said head and at the end ofthe lower leg-section, a bucket-band mounted on said pulleys to travelthrough the leg and discharge into a spout at the head, means fordriving the band-pulley, in the elevator-head, and means for detachablyconnecting the latter to a suitable support, substantially as and forthe purpose set forth.

A bucket elevator, comprising a head and leg, a bucket-band pulley insaid head and a like pulley at the lower end of said leg, a bucket bandon said pulleys, traveling through the leg and discharging into a spouton said head, and means for driving the bandpulley in the elevator-headby power supplied from a source distant therefrom, said head providedwith means for suspending the elevator from hoisting-tackle so as toswing freely in all directions, for the purpose set forth.

4. A portable bucket elevator, comprising a head and leg composed ofseparable sections, bucket-band pulleys mounted in said head and at thelower end section of the leg respectively, a motor within and organizedto drive the band-pulley in said head, means for supplying motive powerto the motor from a source distant therefrom, and a bucket-band mountedon said pulleys to travel in said leg and discharge through a spout insaid head, the latter provided with means for suspending the elevatorfrom hoisting-tackle so as to swing freely in all directions,substantially as set forth.

5. A bucket elevator comprising a head and leg, a bucket-band pulley insaid head and a like pulley at the lower end of said leg, a bucket-bandmounted on said pulleys traveling through the leg and discharging into aspout in the head, an electric motor within the upper band-pulley,gearing connecting the latter with the motor, and flexible eonductorsfor supplying current to the motor from a source distant therefrom; incombination withmeans at. the elevator-head for suspending the same froma hoisting-tackle so as to swing freely in all directions, substantiallyas and for the purpose set forth.

6. A bucket elevator comprising a head and leg, a band-pulley in saidhead and a like pulley at the lower end of the leg, a bucketband havingits buckets secured to one and the same face of said band, the lattermounted on said pulleys to travel through said leg and discharge into aspout on said head, and means for driving the upper pulley; incombination with a deflecting-pulley below the driving pulley organizedto deflect the bucket-band as it leaves said driving-pulley to bring theback of the descending portion of the band close to the back of theascending portion of said band, for the purpose set forth.

7. The combination with the head of a bucket elevator having side platesprovided with journal-bearings; of a framing having journals secured insaid bearings, a drivingpulley loosely mounted on said journals, anelectric motor carried by the framing, gearing connecting themotor-shaft with the pulley and means for supplying current to themotor, for the purpose set forth.
